SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 355,621, dated January4, 1887. Application filed April 1, 1886. Serial No. 197,432 (No model.)

T at whom it may concern.-

Be it known that we, EMANUEL N IOHOLS, of Unadilla, in the county ofLivingston, State of Michigan, and DANIEL W. CLARK, of Grass Lake, inthe county of Jackson and State of Michigan, have invented a new andImproved Spring-Motor, of which the followingis a full, clear, and exactdescription. 4

Our invention relates to the construction of aspring-motor; and itconsists, more particularly, of a peculiar arrangement for acceleratingand regulating the reciprocations of the rock-shaft through which thepower is applied and the invention further consists of a novel 1spring-winding attachment and of certain other details of constructionand combinations of parts to be hereinafter explained, and specificallypointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan. view of our improved spring-motor, a portion of theframe supporting the spring-winding mechanism being cut away to disclosethe construction of the parts. Fig. 2 is a side elevation of the motor,wherein a portion of the parts is shown in section, the View being takenon broken line at x of Fig. 1;

the spring-winding attachment.

In the drawings above referred to, A represents the supporting-frame ofthe several parts of the motor, and at one end of this frame there arearranged hinged vertical posts B, provided with slots in their innerface, in which there are arranged toothed racks O, the upper ends ofwhich are rigidly connected by a cross-bar, D. The posts B are eachformed with upwardly-extending sections 1), which carry a cross head orbeam, E, that is provided with a central threaded socket, a, in whichthere is arranged a vertical threaded shaft, E, the lower end of saidshaft passing through the crossbarD to engage with a nut, c, a collar,d, being formed upon the shaft in position to rest upon the upper faceof the cross-bar.

The main shaft of the motor, which is shown at F, is provided with twogear-wheels, F. F,

and Fig. 3 is a view of the upper portion of that are rigidly mounted onthe shaft, a loose gear, I, and a ratchet-wheel, G, that is en gaged bya pawl, 6, carried by the gear I, said ratchet-wheel being fast on theshaft.

Upon either side of the main supportingframe A there are arrangedauxiliary frames H H, across which the shaft F extends to engage withsprings H, one end of each of said springs being fixed to a cross-rod,as f, that is rigidly fixed in the auxiliary frame, while the other endis secured to the shaft F.

The large gear I engages with a pinion, J, carried by a shaft, J whichshaft also carries a large gear-wheel, J, that engages with a pinion, K,upon a shaft, K, which carries a gear, K, the accelerating-gearing beingcon-- tinued through the gears L .M and pinions L M of the shafts L and.M, respectively, motion being finally imparted to a crank-shaft, N,through its pinion N, said pinion being 7o engaged by the gear M. To oneend of the shaft N there is keyed a balance-wheel, O, that is providedwith a crank-pin, P, which, through the medium of a connecting-rod, Q,is connected to the upwardly-extendingarm R of a regulator, S, that isrigidly fixed to and supported by a rock-shaft, T, which carries alever-arm, U, to which there is fixed the connecting-rod V, leading tothe mechanism which the motor is designed to operate.

The swinging regulator is of peculiar construction, the main body of theregulator consisting of a heavy weight, from which there extends a smallarm, 8, which is fixed to the shaft T, thelower and outer face oftheweighted 8 5 portion of the regulator being substantially concentricwith the shaft T. In addition to the arm 8, the regulator, as abovestated, is provided with an arm, B, said and extending upward in frontof the shaft T, and then forward to engage with the connecting rod Q.

In winding up the springs H, the shaft E v is turned by means of itshand-wheel E so as to force the racks O O downward, thus rotating thegears F F and turning the shaft F 5 and winding the springs H. If thesprings are to be fully wound up, it will of course require more thanone downward movement of the racks; but this movement is readily broughtabout, as, from the construction described, it will be understood thatwhen the hand-wheel E is turned so as to draw the shaft E, andconsequently the racks O 0, up ward the posts 13 can be moved back ontheir pivotal connection, thus releasing the racks G from engagementwith the gears F F, the parts at this time being held by a stop appliedto any portion of the train of gearing or to the regulator.

Unless the springs are very heavy, they might be wound by a simple crankattached to the end of the'shaft F. After the springs have been wound,their action upon the shaft F will cause such shaft to revolve, and thisforward rotary motion of the shaft F will be transmitted through theintermediate accelerating-gearing to the crank-shaft N, which, inrevolving, will impart a reciprocating mo tion to the regulator; and itwill be readily understood from the construction described, andillustrated'in the drawings, that the mo- "tion imparted to theregulator will be by it and defined, owing to the pendulous character ofthe regulator S.

Although this motor is applicable for use in the running of any form oflight machinery, it is designed more particularly for use in connectionwith a pump.

Having'thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a mainspring and its winding mechanism, of atrain of accelerating-gearing, a crank-shaft,N, operated thereby, therock-shaft 'I, having an arm, U, the pendulous regulator S, having anarm, 8, rigidly connected to rock-shaft T, and an arm, R, and the rod Q,connecting the outer end of arm R with thecrank-shaft N, substantiallyas set forth.

2. The combination,with ashaft, F, carrying a fixed ratchet-wheel, G,and connected with. springs H, of gear-wheels F, racks G G, threadedshaft E, a train of accelerating-gearing, substantially as described, acrankshaft,

h, driven by said accelerating-gearing. and a regulator, S,con nected tothe crank-pin Pof the shaft N by arod, Q, and connected to and supportedby a rock-shaft, T, formed with an arm, U, substantially as described.
